BASKET-MAKING MACHINERY.

Specification of Letters Patent.

Application filed April 11, 1910. Serial No. 554,818.

To all whom it may concern:

Be it known that I, JOHN EKLUND, a citizen of the United States, residing at St. Joesph, in the county ofBerrien and State of ichigan, have invented certain new and useful Improvements in Basket-Making Machinery, of which the following is a specification.

This invention relates to basket making machinery, particularly the making of bas kets of oblong form and having rounded ends and tapering sides, known to the trade as the Climax basket.

' One-object of the present invention is to provide a machine for making baskets which comprises a traveling form,,upon which the sides, bottom and circumferential 1100 s are assembled, the said form being move step by step with reference to stapling or stitchingdevices to secure the assembled parts to-- gether; the basket, when completed and removed :from the form, having the requisite shape desired and requiring no further manipu'lation to give it an oblong form.

A further. object'resides in the provision of simplified means for operating the form, 1

to the end that its movements will at all times be accurate and dependable, and its step by step motion be performed with p're-. .ClSlOIl and without lost motion or vibration.

Another object is to provide 'improved means whereby the form is alternately rotated by, and'shifted laterally with relation to its axis.

This specificationis the disclosure of\ one form of. my invention, while the claims define the actual scope of my invention.

Reference is to be had to the accompany ing drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all making machine constructed in, accordance with my invention. Fig. 2 is a front eles shown in Fig. 2.. Fig. 4 is a front iew of the form showing the same in its different positions as it is alternately -shifted upon and rotated byits axis. Fig. 5 is a fra mentary view of one end of the machine ame stem of the strap 10 of theecoentric 11, car

The staple forming and driving devices .6 may beof any suitable 01' approved con- .struction, the reciprocating head 7', being mounted in the usual mannerupo'n the upper enil of a vertically-reciprocztin rod 8, and its lower end p'ivotally mouiite at'9 to the ried by the shaft 4. r 1

The shaft 4 is rovided with a clutch mechanism 12, of w ich the' )art 13 is locked to the shaft-and the part 14 connected with the hub of the free-running drive pulley 15.

Connectionv between the clutch parts is obi tained by means of, a bar 16, one end of which is normally rojecte d'" into engagement with the not es 17 by a spring '18, disposed between its op osite end and the end of the clutch. The a1 16 is provided with a laterally pro'ecting beveled head 19, with the point of t e bevel pointed in the direction of the rotation of the shaft, and

normally positioned in a transverse slot 20,

when the clutchis closed.

Mounted so as the upper end thereof will be normally in the path of tl to slot 20, as the adapted to engagethe beveledheadlQ of the clutch-bar, and shift same so asqt'o open the clutch. The tripping bar 21 has a pin engages a {slot (not shown) in the lever 24, whic. 1 latter is fkeyed to.the rock shaft 25' and opera'ble by the foot treadle 26. The lever 24, and owmg to its connections the tripping-bar 21 and Oct treadle 26, are all normally held elevated by a spring 27, supported by the standard 28, attached to and drawing the free end of said lever upwardly. It follows, therefore, that 'as tlie'clutch is normally open that the machine is normally'at a standstill, the freerunning drive-pulley and the clutch-section connected therewith being the onl parts in motion; and that, in order to obtain a single or successive operation of the staplingheads and corresponding movements of the other mechanism, it is necessary to hold the foot treadle 26 depressed.

Mounted upon the shaft 4 is a wiper cam 29, adapted to intermittently operate a pintooth wheel 30 mounted on one of the standards 2. The said wheel having six pinteeth to correspond with a like number of notches 31 on the periphery of the stop or locking disk 32. The pin-tooth wheel 30 has three cams 33 formed on its periphery, half as many cams as there are pin-teeth 34 on the wheel and notches 31 on the stop or looking disk 32, the object of .which will be presently explained.

The reference numeral 35 represents a friction device'comprising a part 36 which is locked to the shaft 5, and to the hub of which the stop-disk 32 is locked, and a part 37 which is free upon said shaft and to the hub of which the sprocket wheel 38 is keyed. The sprocket wheel 38 is connected by a sprocket chain 39 with a smaller sprocket Wheel 40 on the drive-shaft 4, and an idler 41 is mounted on a pivoted bracket 42 and engages the chain to steady the same; a helical spring 43 encircling the bracket hub, one end of which is connected to the machine frame and its opposite end embracing the bracket arm, and holding the idler in yielding engagement with the sprocket-chain. The friction device member 36 has sockets 44, formed therein to receive. springs 45, adapted to press against a disk 46, which is held against rotation independently of the member 36, but capable of lateral movement upon the shaft, the pins 47 engaging corresponding sockets 48 in the disk to prevent independent rotation. The member 36 is locked to the shaft 5, and the stop or locking disk 32 keyed to the hub portion 49 thereof, so that the intermittent rotation of theshaft 5 is controlled by the stop-disk. The

member 37 of the friction device comprises a disk 50 having a hub portion 51, upon which the sprocket wheel 38 is mounted, wood fiber or other suitable friction disks 52 and 53 being interposed between the disks 46, 50 and a. cap 54, whichlatter is bolted to the member 36, and removable so as to replace the fiber or other friction disks when worn. The action of the springs 45'serve to hold the free and keyed members of the friction device in strong frictional contact with each other, so as to transmit power from the drive shaft 4 to the shaft 5, b means of the sprockets and chain hereto ore described. However, the shaft 5 is only so driven when not held against rotation by the stop or looking disk, above referred to, the rotation of shaft 4 being constant when machine is in operation, and that of the shaft 5 intermittent. The stop or locking disk is controlled by the pin-tooth wheel 30 which is rotated once while the wiper-cam 29,'which operates same, revolves six times, the operation of the stapling mechanism corresponding to the rotation of said cam, both being operated by the same shaft. As a staple is driven each time the wiper-cam revolves, and as it is necessary in the use of a form or work holder operated alternately with intermittent rotation and intermittent lateral shift, that the shaft which turns the form be held stationary during the shifting of the form, a tripbar 56, forked at its lower end to straddle the hub of the pin-tooth wheel to hold same in proper relation therewith, and having its upper end passingthrough a guide bracket 57 and provided with a dog 58 to engage the notches of the stop or looking disk, is timed in its operation by the three cam members 33 on the pin-tooth wheel, which engage a cam wheel '59, carried by the trip-bar 56, and cause the said bar to beshifted and interini'ttently release and lock the stop-disk three times in succession, which causes the shaft 5 to operate correspondingly, and turn the form or work-holder mounted at the end thereof. The pin-tooth wheel is next given a sixth of a turn three times in succession by the wiper-cam, and as there are no cams on said wheel corresponding with the pin-teeth thus engaged to raise the trip-bar, the stopdisk remains locked and the shaft 5 stationary, during which time the form is shifted laterally, by means hereinafter described, in three successive steps, as lainly shown by dotted lines in Fig. 4. The orm is always stationary as the staples are driven, and the rotation and shifting of the form occurs during the intervals between the driving of the staples, the stapling devices oper-- atlng three times during each shift and rota: tion or twelve times in all for a complete revolution of the form.

The form or work-holder 61 upon which the basket material is assembled and held to be stapled together, has "an exterior shape corresponding to the shape of the finished "basket, and comprises slightly tapered par-- allel sides and rounded ends. The rear wall 62 is provided with a slot 63 adapted to re? vceive the flat head 64 on the shaft 5, which head serves to turn the form and also permits. same to be shifted thereon, said head having parallel guiding faces or elements upon which the form is mounted to slide in its shifting movement. The front wall 65 of the form is provided with a slot 66 someamass:

what larger than the slot 63, and a friction roller 67 1s mounted on the end of shaft with its inner end bearing against the rear wall to hold the form against movement longitudinally of the shaft, the ed es of the slot 66 riding thereon to support t e form. The

sition as it is shifted with relat1on to then shaft and to prevent play and wabbling as the form is turned by the shaft, see Fig. 4. To further steady and hold the form as it travels, the rear'wall thereof is kept in frictional contact with the side of the guideplate, by the use of expansion springs 72 carried 1n the sockets of the head 73 hearing against a friction disk 74 inter osed between the head 73 and the shaft bearing 75, the action of the springs causing a steady pull or thrust of the shaft to draw the form against the guide-plate. The friction disk 74 carries a pin 76 fitting into a socket in the head 73, so that the disk will rotate with the head 73 which is locked to the shaft. Wood fiber or other suitable friction disks may be inter osed between the disk 74 and the bearing 15,50 as to prevent wear of metal arts, such fiber disks being easily replaceab e when worn. A similar friction device 80 is used to hold the pin-tooth wheel 30, which is mounted for rotation upon a fixed shaft, against movement by vibration of the machine or otherwise. A'lever 81 fulcrumed at 82 has a feed pawl 83 connected to its u per end, with the free end of the pawl ri ing upon the rim 84 and engaging the notches 85 of the form to shift the same, the lever carrying a cam roller 86 at its lower end which engages the cam 95. The cam roller is held in engagement with the cam, 95 by a spring 87, and the lever is actuated upon each revolution of the shaft 4, but as the rim of the form is only provided with three notches on each fiat side, the feed pawl is not in operative engagement with the form during the time the same is rotated by the shaft, but serves to shift the form only when in a horizontal position.

In order to properly guide the hoop strips or hands and hold same in proper position upon the veneer forming the sides as the form is actuated, guide-members 88 having a slot 89 through which the hoops or hands are drawn, are mounted upon a rock-shaft 90, en ported by a bearing 91; The rockshaft lies a lever 92 mounted on one end, which is connected with a similar lever 93 on the treadle-shaft by a connecting rod 94 so that, when the treadle is depressed to operate the machine, the guide members wlll be automatically rocked so as to lower the feed ends and hold down the hoo ps or hands in proper position upon the V811! er forming the basket sides, to receive the st a les which secure the parts together. When t e treadle is released the guide-members are automatically raised to provide a cleararce space to ermit the basket to be withdraw n from the orm.

In operating the machine, the veneer forming the basket sidesis positioned upon the form, with the bottom board held against the form, either manu tlly or by any suitable mechanical means employed for'that purpose. The ends of the hoops are next inserted-through the guides and properly positioned upon the yeneer, and the first staples driven to secure the parts together. Upon depressing the foot-treadle the clutch mechanism will be clos ed and,

suming the starting point'of tlieform to be the position shown in full liiles in Fig. 4, the same will be shifted longitudinall in three successive steps, by the feed paw and staples driven after each shit .t. At this point the form has reached is extreme movement to the left, and the cams on the pin-tooth wheel now release the stop-disk three times in succession, thus pausing the form to be turned by the shaft, a 1d brought backto its original longitudinal position in three distinct moves. Theform :s provided with twelve clench-blocks .p'rope rly spaced upon each edge, and the machire is timed so as to operate and bring the clonch-blocks under the stapling devices b alternately shifting the form the proper isaanoe three times and turning the form in ti ree suoces sive steps, a repetition of whicl gives the form a full turn, so as to present all sides head for linear movement in a path trans-- verse to the axis thereof, means )r periodically imparting revoluble moven entto the head, and means including a reciprocating member for imparting step by step linear movement to the form. t
